Question

3. AGE Justine is 13 years younger than her uncle Stewart. Stewart is

18 years older than Justine's sister, Hana. Hana's mother is 8 years older
than Stewart, and 28 years older than her youngest child, Jared. If Jared
is 12 years old, how old is Justine?​

Answer 1

19

Step by step :

If we say Justine is x years old than her uncle Stewart would be x + 13 years old

Stewart is 18 years older than Hana so Hana's age is x + 13 - 18 = x -5

If their mother is 8 years older than Stewart than she is x + 13 + 8 = x + 21 years old and this is 28 more than 12

Then we can say the mother is 40 and x + 21 = 40 ➡ x = 19 we said Justine is x years old therefore her age is 19
